for the collection of metering data under clause 4.3.2 to the extent that its

costs of collection are higher than they would otherwise be.

4.3.4. The person responsible for the metering installation must use its best

endeavours to ensure that interval energy data or accumulated energy data

is:

(a) collected from all metering installations at least quarterly or, where a

greater frequency has been agreed with a customer or a customer’s

retailer, at that greater frequency; and

(a) is required under clause 4.3.4(a) to use its best endeavours to collect

interval energy data or accumulated energy data from a metering

installation at least quarterly; and

(b) has not obtained an actual meter reading in respect of that metering

installation for three successive quarters by reason of the denial of

access to the metering installation by the customer,

then the person responsible must use its best endeavours to obtain an actual

meter reading in respect of that metering installation for the subsequent

quarter.

4.3.6. When interval energy data or accumulated energy data is not collected by a

person responsible for the metering installation from a metering installation

by way of an actual meter reading at the applicable meter reading frequency

under clause 4.3.4(a), an estimated read must be obtained by the person

responsible for the metering installation.

4.3.7. An estimated read obtained for the purposes of clause 4.3.5 must be provided

meter in accordance with clause 2.3, the person responsible for the metering

installation must ensure that metering data for the unmetered connection

point is calculated in accordance with the distributor’s procedure which should

be based on a methodology in the Metrology Procedure. If the unmetered

connection point does not have a predictable load pattern, then the person

responsible for that metering data must have regard to the methodology in

the Metrology Procedure when calculating the metering data at such

connection points
